But the Google Custom Search API is a different thing. It's a search based on a set of sites. What's important is to have an API to search for the "whole" indexed Internet, and Google is the most advanced search engine in town. If you play with more complex queries you quickly note the difference between Google and Bing, Yahoo or Blekko.

Yes, which is what we thought too. But, you can setup a "custom search engine" with some default site (we used www.google.com), then change the settings to that it uses the entire web, and remove the site that you originally put in.

The Bing and Yahoo APIs are definitely a lot better, IMO. But, as long as Google wants me to use their Custom Search API, then that's what I'll use.
